Question

Find k, if one root of the equation 5x + 6x + k = 0
is five times the other.
​

Answer 1

Answer:

K=1

Step-by-step explanation:

eqn is 5x^2+6x+k=0

let one root be a then

a+5a=-b/a

6a= -6/5

a= -1/5 put the value of a instead of x

5(-1/5)^2+6(-1/5)+k=0

1/5+(-6/5)+k=0 add both the rational terms

-5/5+k=0

-1+k=0

k=1
